Promising review: “This is the best thing you never knew you needed. I own a digital clock with the numbers displayed in red LED light, and every night I’ve blocked the light with a cover so it doesn’t shine in my eyes as I sleep. Silly, I know, but I like my room pitch black and cave-like. On a whim, I bought this product. OH MY GOD! Game-changer!! For the first night EVER, I didn’t have to cover the clock display before I went to bed!! I had no idea how big a difference this little dimmer could make, but I’m more than pleased with the result. I can still see the time display just fine, but now my room is a happy cave! Some commenters argue you could get the same effect using electrical tape, but this product is easy to remove and doesn’t leave a sticky residue at all, which can’t be said for most tapes. I did notice a slight lag in response when I covered my TV LED sensor, so if you’re trying to block something that actually senses inputs, I would maybe not suggest this. Other than that, excellent product!” —Amazon Customer
Get a sheet of more than 100 stickers of varying shapes and sizes on Amazon for $1.49 (also available in a blackout version). These larger dimming sheets from Amazon are $8.29 for two 6-by-3-inch stickers and work wonders if you’re trying to cover a larger surface area, like a clock face.
